  • Treatment of Mixed Sulfide Oxide Ores of Copper

    Many of our largest copper deposits contain both sulfide and oxidized copper minerals. The large porphyry mines, with a total copper content of from 1.3 to 2.0 per cent., send to their mills ore with an oxide content of from 0.2 to 0.4 per cent.

    Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching.These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be concentrated using ...

    N-octyl hydroxamate collectors such as AM28 can be used successfully to recover the oxide mineral component in mixed copper sulphide/oxide blends without reducing the recovery of the sulphide minerals. This investigation showed that for a Minto composite blend of 70 wt% sulphide and 30 wt% oxide, the rougher scavenger copper recovery was 95.5%.

  • Flotation of mixed oxide sulphide copper-cobalt minerals ...

    With mixed oxide-sulphide ores, it is accepted practice to concentrate sulphide and oxide minerals in separate flotation processes. While flotation is a common method to concentrate sulphide ore in the DRC, oxide ore requires sulphidisation prior to flotation with xanthate collectors (Crundwell et al., 2011).
